T 0 all whom it may concern:

bearing sleeves are resiliently clam ed in Be it known that I, HAROLD M. SOHEIBE, ii

their sockets by means of convex was ers 18 a citizen of the United States, and a resident of Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Dynamo- Electric Machines, of which the following is a specification.

M invention relates to dynamo-electric mac ines, and ithas for its object to provide such a structure and arrangement of the parts of a machine that it may be readily.

assembled and dismantled without disturbing permanent connections upon the interior thereof.

Figure 1 of the accompanying drawings is a view; partially in plan and partially in section, of a machine constructed in accordance with my invention. Fig. 2 is a diagrammatic view illustrating the circuit connections of the machine. Fig. 3 is a vertical sectional view, through one of the bearing: Fig. 4 is a transverse sectional view t ough one of the brush holders, and Fig. 5 is 8. pers ective view of one of the parts of the mac 'ne.

The machine comprises. a laminated field magnet core 1 that is inclosed and supported by a closely fitting sheet-metal casing 2 and is rovided with a Winding comprising two series-connected coils 3 and 4. Projecting entirely through the core structure are bolts '5 upon the projecting ends of which insulating blocks 6 and 7 are screwed. Secured,

. b means of screws 8 and 9, to the insulating b ocks 6 and 7 are resilient U-shaped clips 10 and 11 that constitute the terminals of the motor parts contained within the casing '2.-

for a s aft 17 upon which the rotatable member of the machine is mounted. The

mutator cylinder 27 and an insulating sleeve :28 that surrounds the said metallic sleeve and is slotted upon opposite sides at 29 to expose the metallic sleeve. WVhen the cover 14 is applied to the casing 2, the U-shaped clips or terminal devices 10 and 11 project into the slots in the insulating sleeves 28 and clamp upon the metallic sleeves 25, the brush holders being in this manner connected to the terminals of the motor parts contained within the casing 2. This structure obviates the necessi-ty of manually connecting and disconnecting the brush holders to and from the otherparts of the machine before applying or after removing the cover 14, and thus renders the machine susceptible of very ready assembling or dismantling for inspection and repairs.

I claim as my invention:

1. In a dynamo-electric machine, the combination with a casing havingseparable parts, and field magnet and armature structures within the casing, of terminal devices supported by the field magnet structure and electrically connected respectively, to a terminal of the field magnet winding and to 'a terminal of the machine, and brush holders carried-by one part of the casing and adapted to be engaged by the said terminal devices.

2. In a dynamo-electric machine, the combination with a casing havin r separable parts, of stationary and rotatab e members within the casing, terminaldeviccs secured to but insulated from the stationary member, and brush holders carried by one part of the casin andada ted to be en a ed respcc-" 'tively, by the said terminal devices.
